15 - Pell-Mell (1695) A game formerly common in England, in which a wooden ball was driven with a mallet through an elevated hoop or ring of iron. The name was also given to the mallet used, to the place where the game was played, and to the street, in London, still called Pall Mall. The word may have been derive from pelle {a shovel} + m[^e]ler {to mix}, as when different kinds of grain are heaped up and mixed with a shovel. See {Pell} shovel, {Medley}.]
I am absolutely certain that it ain't Hatfield House. I have also danced there (in fact we were banned!). Hatfield House, as it is now, was built in 1611. This one is still there (what's left of it).
